The W1027 is a high-gain, omni-directional external antenna for 2.4 GHz wireless devices. It operates in the 2.4 to 2.5 GHz frequency range, providing a peak gain of 3.2 dBi with a nominal impedance of 50 ohms and a VSWR of 1.9 or less. This antenna features a one-quarter wavelength dipole configuration with vertical polarization, which produces a broad, 360-degree omni-directional radiation pattern. The W1027 is ideal for WLAN devices using WiFi (802.11b/g), Bluetooth, and ZigBee protocols, and is well-suited for point-to-multipoint broadcasting where uniform coverage is required.
